How are Emergency Room wait times calculated?Our Emergency Department wait times, called “Door to Doctor” represent the average estimated length of time from registration to being assigned a doctor, nurse practitioner or physician assistant. The wait times displayed on this site are refreshed every 15 minutes. Many circumstances can affect wait times. Patients with life-threatening conditions will be seen before those with less-serious problems or ailments. These times are provided for informational purposes only and cannot be guaranteed upon arrival. They may be subject to change without notice.
